The computer can t be turned on, and it always restarts once, why?

Hello! First of all, teach you to eliminate it by hand.

1.Take out the battery of the motherboard, buckle it back, and discharge it. Purpose: To restore the default values of the BIOS settings and eliminate the automatic reboot or shutdown of the BIOS cooling presets.

2.Sweep the dust inside the chassis to eliminate short circuits or poor heat dissipation caused by excessive dust.

3.You see if the CPU thermal grease is dry, silicone grease is used to improve heat dissipation ability, if there is no silicone grease, it may cause heat to not be dissipated, and the machine will automatically shut down. A few dollars for a pack, note:

If there is too much thermal grease and it is too thick, it will form a film in the middle of the contact surface, which will hinder the direct contact of the metal, which is worse than not applying thermal grease.

4.You can think about whether the fan size or fan capacity is no longer enough for high-end computers. First consider the size of the fan (the bigger the better), then the power (the bigger the better), and the manufacturer.

5.The rest is due to other objective reasons, such as high indoor temperature, running large programs (games) for a long time when booting up, poor heat dissipation of the case, poisoned CPU usage often 100, etc. It is recommended to search for everest in it, and put this software down (without installation) to the computer-> sensor-> you can see the hard disk temperature, CPU temperature, fan speed, etc., my fan speed is 3500, no noise, for your reference!

1. The operating system is overloaded, and the software is set to automatically restart to achieve the purpose of optimization, but the average home user rarely has a similar situation.

2. When the power supply API management module fails, or the power supply itself fails, when the system load is too large, resulting in a sharp increase in virtual memory (your physical memory is too small), and the hard disk and CPU load are accelerated and too heavy, the power supply cannot withstand the voltage increase due to the fault, resulting in self-power outage and shutdown.

According to your usage situation, it is recommended to install genuine anti-virus software, such as Kingsoft Antivirus or Rising after increasing the memory, and try to avoid virus invasion due to network use and system shutdown or crash. Because in the case you mentioned, there is also a high possibility of failure due to the use of the same network service.

The display is aging due to the damp tube header.

Desktop or laptop? It could be that there is a problem with the fan.

The computer needs to be turned on and restarted+ and then it won't be opened.

The computer needs to be turned on and restarted + and then it can't be opened, <> the reason why the computer has been restarted and can't be opened: 1. Computer hardware failure solution: After the computer presses the boot button, the signal lights will light up, and the screen will also light up, which means that the computer is only a problem with the software, and there is no problem with the hardware; If the signal light or screen does not light up, it is a hardware failure, and you can contact the official after-sales maintenance warranty directly.

2. Solutions to computer infection virus or system damage: 1. Press the F8 key when booting up to enter the safe mode of the computer, and select "Last correct configuration". 2. If the 1-step method is useless, or after pressing F8, you can't enter the interface in the above figure, then the solution is to reinstall the system, find a system disc and reinstall it. 3. Hardware problem solution:

There are many kinds of hardware problems that cause your computer to keep restarting, such as lack of power output, high CPU temperature, corrupted cache, loose graphics card, and more. Direct warranty is sufficient. Fourth, if there is a problem with heat dissipation, if there is dust and foreign objects blocked, resulting in poor heat dissipation, there will also be repeated reboot and restart of the computer, you can clean it up, and go to the computer store to clean it up.

Fifth, the voltage is too high, the voltage is too high, if its fan, U disk, CPU temperature is too high, this situation will also occur, you can let the computer rest for a while, and then turn it on. Hope it helps!

The computer has been restarted repeatedly, and the reasons for not being able to turn on may be: incompatible drivers, high CPU or other hardware temperatures, bad sectors on the hard disk, power failures and voltage instability, described in detail as follows:

1. Incompatible drivers can also lead to restart. It is necessary to restore the system or reload the system.

2. Caused by high CPU or other hardware temperatures. In this case, you need to power off the computer and wait for the temperature of the console to drop before restarting.

3. The hard disk has bad sectors, which may be because the host has been impacted, you can use the system's own functions or software to repair the disk, or format the hard disk to repartition and reinstall the system.

4. Power failure and voltage instability can also cause automatic restart. You need to check whether there is a problem with the socket connected to the computer, and if there is no problem with the socket, you can take it to the computer store for inspection.

Precautions: 1. Don't put too much sundries next to the computer, as it will not be able to dissipate heat normally for a long time, which will affect the efficiency of the computer.

2. During the use of the computer, the number of cold starts of the system should be minimized, and the time interval between continuous opening and shutdown should be appropriately extended to avoid the backlash voltage and affect the service life. <>

If you can restart it several times, congratulations to the host capacitor burned, at first, it can be turned on several times, and then it can't be turned on indefinitely.
